Allure's own office at One World Trade Center was the setting for Alba's fourth cover and profile shoot for the magazine. The glass-and-steel skyscraper was the perfect backdrop for an actress who's also a businesswoman. That's her cover look here.

Alba's sexy look was inspired by Faye Dunaway in Network.

To keep Alba's waves perfect during the long day, hairstylist Orlando Pita used hot rollers from the '70s. "They're wrapped in velvet and have wax cores that curl better. New models cool too quickly," he says.
